• We developed the methodology for a community survey to determine the prevalence of emotional and behavioral disorders among children 4 to 16 years of age in Ontario, Canada. Our discussion includes the objectives of the survey, the measurement of disorder, sampling methods and survey design, and a description of the data collected and instrumentation. Among 2052 households with eligible children, 1869 (91%) participated in the survey. The results can be used to help plan the future allocation of mental health resources In Ontario.
